Double pass printing for solder paste is not needed and will cause defects. Redesign your stencil thickness or aperture sizes, change your paste mesh size or type, go to 45 degree blades.

Hi, The machine is a Universal GSM1 flexhead. Is it possible to just change the lens of a 2.6mil camera for a 1mil or 0.5mil lens. Or do I have to buy a complete camera assembly to do this? Thanks, Grant

Hey, and guess what? A CP6-4000 will do the same thing. Fuji hasn't changed that technology one iota since the CP3 days.

As a minimum, we clean the printer setup every shift change. Probably the best advice on this is from your paste supplier.

Peter, We have 2 Fuji lines. We run from 5 to 5000 piece lots. When we are running near capacity and have a lot of change-overs scheduled we have special operators that will load parts onto feeders and organize the feeders like they will be on the

Your warpage problem could be caused by change in: * Multilayer board construction (not homogeneous or unbalanced - too resin rich or poor) * Supplier process capabilities (lamination cycles) * Material selections (usually cheap and dirty), etc.

It sounds like this part is floating on your solder joint during reflow. You may need to redesign your pad geometry. In general with this type of clip - smaller pads are better. If you cannotcahnge pad size, try changing the openings on your stenc

Qsoft will accept a negative theta on import and change it to a positive theta. For example cad data with a -90 theta will appear as 270 theta after import.
